Hi,

Does D support any form of reflection or RTTI? I didn't see any mention of
this on the webpage.

thanks -mike

There's some support for it already. For any object you can allways get a ClassInfo structure and see the name of the class, wich class is it's parent and wich interfaces it implements: import stream; File f = File(); ClassInfo fci = ifile.classinfo; printf("Class name: %s\n", fci.name); printf("Base class name: %s\n", fci.base.name); There's a pointer to the vtable, contructors, destructor and invariant methods. What I'm missing the most is the capability to see a class' methods and read wich parameter types they need... but this seems quite difficult in a native code compiled language. You can see the ClassInfo source in /dmd/src/phobos/object.d

methods.

contructors is not available!!
